this would require some encryption and still can be intercepted. Any ideas how to fix that?

No, I'm talking about anyone with SS7 access basically has root on the whole network and can query for locations of any phone number anonymously... no audit trail, no access control.

right, that's how police and criminals do it, I am aware how it works, what I wonder is how do you fix it, replace the protocol? encrypt it?

Why when we have bandaids like ss7 firewalls.
